A denial in the country, for example (8)
I believe the answer is:
negation
'a denial' is the definition.
(I know that negation is a type of denial)
'in the country for example' is the wordplay.
'in the' is an insertion indicator.
'country' becomes 'nation' (synonyms).
'for example' becomes 'e.g.' (short for 'exempli gratia', 'for example' in Latin).
'nation' going around 'eg' is 'NEGATION'.
(Other definitions for negation that I've seen before include "people" , "Contradiction" , "Denial of something's existence" , "One giant turns out to be a denial" , "Making denial" .)
